Embodiment Construction

[0023]FIG. 1 shows a perspective view of an instrument panel 1 as an embodiment of the component for motor vehicles according to the present invention. The instrument panel 1, which can also be produced from a hard plastic material, shows an airbag cover 2 of elastic plastic material. The airbag cover 2 is disposed in the area of the deployment channel 3, which serves as a receptacle of an airbag not shown in FIG. 1. The airbag cover 2 covers the deployment channel 3 and exhibits a single weakened zone 6 extending preferably centrically between opposite walls 4, 5, which delimit the deployment channel 3, and extending relatively far, for example about one half of each the distance of the walls 4, 5, beyond each of the walls 4, 5 that serve as a delimitation of the deployment channel. The weakened zone 6 is formed, for example, by providing a slot or a recess in the surface of the instrument panel 1 facing away from the interior of the vehicle.

Abstract

The invention concerns a component (1) for motor vehicles, in particular, instrument panel, lateral covering or side member covering, comprising an airbag cover (2) arranged in the region of the filler channel (3) and having a weaker resistance zone opening when the airbag is inflated. The covering zone located on either side of the weaker resistance zone can move freely, from an extracted airbag, along a clearance path while remaining linked to the component 91), after the airbag has been inflated, in specific manner. The airbag cover (20) is an elastic material. The weakened resistance zone extends over the opposite delimitations (4, 5) of the filler channel 93), so as to ensure the extension and inflation of the airbag. Said device eliminates possible damage to the inflated airbag and injury risks incurred by passengers as result the burst parts projected coming from said cover.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to a component for a motor vehicle, in particular an instrument panel, side panel or support panel with an airbag cover, which is arranged in an deployment area associated with a deployment channel and which is provided with a weakened zone that will open upon release of an airbag, wherein areas of the airbag cover located on either side of the weakened zone are movable for clearing the deployment path of the releasing airbag and remain attached to the component after the airbag has inflated.[0002]A component of this type is known from EP 0583 079 A1. The afore-described component configured as an instrument panel shows an airbag cover which is arranged in the deployment channel and which is configured as a unitary piece with the instrument panel, which is of a rigid foam material. A weakened zone in the airbag cover is formed through a material reduction which, upon deployment of the airbag, breaks open under formation of two w...
